I’ve got three to choose from. I have the Mossberg 590 Mariner that I bought first. 8 + 1 shot, loaded with 12ga 00 buckshot. Then I got a Mossberg Shockwave 12 ga. It is also loaded with 00 buckshot. My most recent purchase is a Standard Manufacturing DP-12. It is the 12ga double barrel pump shotgun that holds 16 rounds of 12ga 2 3/4 inch 00 buckshot. It looks like a “bullpup” gun. Looks like it will be pretty intimidating.
